Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an air conditioner having a suction grill.

[0002]

2. Description of the Related Art FIG. 5 is a side view showing the configuration of a conventional general air conditioner. In FIG. 5, reference numeral 51 denotes a base, and a front panel 52 is attached to the base 51 to form a box-shaped housing 53. A detachable suction grill 5 is attached to the front panel 52 located on the front surface of the air conditioner. The suction grill 5 is formed with a plurality of air intakes 50. Further, 54 is a removable air filter, 55 is a heat exchanger, and 56 is a cross flow fan.

The suction grill 5 can be opened and closed with respect to the front panel 52 by rotating around a support shaft 57. Further, a plurality of air intake ports 58 are also formed on the top surfaces of the front panel 52 and the base 51.

As described above, in recent air conditioners, a plurality of air intakes are formed in the front panel 52 and the top surface of the base 51. Therefore, the air sucked from each air intake when the air conditioner is operating flows along the path shown by the arrow in FIG.

[0005]

When the air flows as described above, dust or the like carried with the air adheres to the top surface of the air conditioner (the front panel 52 and the base 51), and the air conditioner. When used for a long time, the top surface becomes dirty due to the accumulation of dust and the like.

However, in order to clean the top surfaces of the front panel 52 and the base 51, especially the rear surface of the rear part, in the case of the conventional air conditioner, not only the intake grill 5 but also the front panel 52 is replaced by the base 51. It is necessary to completely remove the filter 54 and the filter 54. Then, the cleaner cleans the top surface by inserting a hand from the upper part of the opening opened by removing the front panel 52.

As described above, in the conventional air conditioner, in order to clean the top surfaces of the front panel 52 and the base 51, the above-mentioned troublesome work is required.
Therefore, there is a demand for an air conditioner that can easily clean the top surface.

An object of the present invention is to provide an air conditioner capable of easily cleaning the top surface.

[0009]

In order to solve the above problems and achieve the object, the air conditioner of the present invention is configured as follows. (1) In the air conditioner of the present invention, a main body is composed of a base and a front panel, and a heat exchanger and a fan are provided inside the main body, and indoor air is sucked from the front surface and the upper surface of the main body. In an air conditioner that blows out temperature-controlled air from the lower part of the main body, a guide portion provided on both sides of the front panel so as to bend from a front surface to an upper surface of a suction grill that is detachably attached to the front panel. It is possible to insert along. (2) The air conditioner of the present invention is the air conditioner according to the above (1), and the suction grill is composed of a plurality of horizontal rails and bendable columnar ribs connecting the horizontal rails. (3) The air conditioner of the present invention is the air conditioner according to (1) above, and the suction grill is configured by connecting a plurality of horizontal rails in a bellows shape. (4) An air conditioner according to the present invention is the air conditioner according to any one of (1) to (3) above, and further includes a magnet for fixing the suction grill at an insertion end position of the guide portion or the main body or One of the suction grilles is provided, and the other is provided with an iron-based plate to which the magnet is attracted.

As a result of taking the above-mentioned means, the following actions are brought about respectively. (1) The air conditioner of the present invention includes the suction grill,
Since it is possible to insert along the guide portions provided on both sides of the front panel so as to bend from the front surface to the upper surface, when the suction grill is inserted, part of the suction grill is part of the air conditioner. It corresponds to the top. Therefore, cleaning the top of the air conditioner
This can be achieved by a cleaner removing the suction grill from the air conditioner body and cleaning the inside of the upper portion of the suction grill. (2) The air conditioner of the present invention includes the suction grill,
Since the plurality of horizontal crosspieces and the bendable columnar ribs connecting the crossbars are used, when the suction grill is attached or detached, the suction grill can be bent along the shape of the guide portion by bending the columnar ribs. Further, since the horizontal rails are supported by the columnar ribs, the entire suction grill becomes solid. (3) The air conditioner of the present invention comprises:
Since a plurality of horizontal rails are connected in a bellows shape, when the suction grill is attached or detached, the connecting portions of the horizontal rails connected in a bellows shape are bent so that the suction grill has a shape of the guide portion. It becomes possible to bend along. (4) In the air conditioner of the present invention, a magnet for fixing the suction grill at the insertion end position of the guide portion is provided on one of the main body of the air conditioner and the suction grill, and the iron attracted by the magnet is attached to the other. Since the system plate is provided, the suction grill can be fixed to the main body with a simple structure.
